Abstract

The invention belongs to the technical field of water proofness of tunnels, and particularly provides a prefabricated waterproof structure of a deformation joint of an open-cut tunnel and a method. Afirst elastic sealing piece and a second elastic sealing piece are correspondingly and fixedly arranged on a first steel pedestal and a second steel pedestal; the first steel pedestal is connected with the second steel pedestal through a connecting bolt to form a waterproof structure body; the first elastic sealing piece and the second elastic sealing piece are extruded to fill the deformation joint in the middle of the waterproof structure body; and finally, concrete is cast on two sides of the waterproof structure body to complete the construction of the waterproof structure in the tunnel. The waterproof structure can omit the welding of waterproof rubber, and the condition that a waterproof weak link is added during the construction process of the waterproof structure is effectively avoided at the deformation joint part of the tunnel, so that the condition that a connection joint between waterproof materials weakens the waterproof materials of the structure is avoided, and the overall waterproof performance of the structure is ensured; and the existing deformation joint waterproof structure is improved, and the waterproof failure caused due to vibration during the construction process is avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel waterproofing, and in particular relates to a prefabricated waterproof structure and method for deformation joints of an open-cut tunnel. Background technique [0002] Tunnel is a structural type with a large slenderness ratio. Due to changes in geology and foundation properties, even under the same structure and covering soil, the deformation of the tunnel structure foundation will be different. When there are drastic geological changes or sudden changes in the shape of the structure, the uneven settlement of the foundation will be more obvious, and the damage to the structure will be greater. In order to adapt to the deformation of the structure, it is necessary to set a deformation joint at a certain distance. [0003] The structure at the deformation joint is in a discontinuous state. For the tunnel structure buried underground, this will form an obvious water seepage channel. Therefore, in the...
